Purpose: Persistent sciatic artery (PSA) is a rare congenital vascular malformation with an incidence of approximately 0.025% to 0.04%. Persistent sciatic artery has major complications, such as aneurysms, thrombosis, and occlusion. Complications may lead to a range of serious clinical problems, and a timely diagnosis of this vascular variant is crucial to avoid life-threatening complications.
Case: A 65-year-old man was admitted to the hospital with pain and chills in the right lower extremity for 2 months, which gradually worsened. This was accompanied by numbness in the right foot for the last 10 days. Computed tomography angiography showed that the right inferior gluteal artery and right popliteal artery of the right internal iliac artery were connected, which is considered a congenital developmental variant. This was complicated by multiple thromboses of the right internal and external iliac arteries, and the right femoral artery. After admission to the hospital, the patient underwent endovascular staging surgery to relieve numbness and pain in the lower extremities.
Conclusion: Treatment strategies can be selected based on the anatomical characteristics of PSA and superficial femoral artery. Asymptomatic patients with PSA can be closely monitored. Surgery or individualized endovascular treatment plans should be considered for patients with aneurysm formation or vascular occlusion.
Clinical impact: For the rare vascular variation of the PSA, clinicians must make a timely and accurate diagnosis. Ultrasound screening is essential, which requires experienced ultrasound doctors to be aware of vascular interpretation and develop personalized treatment plans for each patient. In this case, we adopt staged a minimally invasive intervention to solve the problem of lower limb ischemic pain for patients. This operation has the advantages of rapid recovery and less trauma, which has important reference significance for other clinicians.

Purpose: Duplex ultrasound (DUS)-measured peak systolic velocity ratios (PSVRs) are commonly used to evaluate arterial stenosis in lower extremity artery disease (LEAD). However, these measurement methods have not yet been standardized. This study aimed to reveal the influence of measuring methods on PSVR values.
Methods: A 132 femoropopliteal lesions with PSVR ranging from 1.5 to 3.5 evaluated using method A (angle correction 60°, the direction of blood flow, the no or few atherosclerotic changes closest to the lesion proximal side was defined as the nonstenotic area) were included. The following 4 different methods were then compared with method A: method B, angle correction 45°; method C, angle correction 60° measured along the vessel wall; D, angle correction 60°, with the nonstenotic area the lowest peak systolic velocity area; and E, angle correction 60°, with the reference point fixed at 2 cm proximal to the target lesion area. The difference in PSVR values was analyzed using the Bland-Altman method.
Results: The mean PSVR value measured by method A was 2.27±0.51, those measured by methods B, C, D, and E were 2.21±0.55, 2.31±0.66, 2.34±0.63, and 2.11±0.63, respectively. The 95% prediction intervals of the differences in PSVR measurements versus A were -0.64 to +0.53 for method B, -0.59 to +0.68 for method C, -0.77 to +0.91 for method D, and -1.12 to +0.79 for method E.
Conclusion: PSVR values considerably differed between measuring methods. PSVR values by DUS are largely dependent on the measurement methods, which could considerably affect the judgment of LEAD.
Clinical impact: Due to differences in several DUS measurement methods, the PSVR results could be changed. Therefore, to need further investigations and unification of measurement method.

Purpose: To evaluate the closure success rate's outcomes with suture-mediated vascular closure device Perclose ProGlide in patients undergoing aortic or iliac artery endovascular repair using large delivery systems (>21F).
Materials and methods: We screened all the patient records in aortic databases at 2 centers who had undergone vascular interventions via ProGlide for percutaneous femoral access >21F between 2016 and 2020. Patients were divided into 2 groups according to the delivery system size: large (L) (22F-23F) and extra-large (XL) (24F-26F). Demographics, anatomical details, and outcome of percutaneous access were evaluated.
Results: Included were 239 patients: 121 in the L group and 118 the XL group. Intraprocedural conversion to open surgery because of bleeding was necessary in 2% L and 6% XL patients (p=0.253). Severe femoral artery calcification was the sole risk factor for converting to open surgery (odds ratio=23.44, 95% confidence interval=1.49-368.17, p=0.025). In all, 2% of L and 3% of XL (p=0.631) did require late percutaneous intervention due to stenosis (all treated with balloon angioplasty). Overall, 3% developed pseudoaneurysm treated conservatively in all except one patient requiring surgical repair. Hematoma and groin infection were observed in 9% and 1%, respectively; none required surgical therapy.
Conclusion: A femoral arterial defect after accessing the artery via a large bore sheath (22F-26F) can be closed successfully with ProGlide in more than 90% of patients. Severe femoral artery calcification is a risk factor for conversion to open surgery caused by bleeding.
Clinical impact: This study adds evidence on efficacy of accessing the artery via a large bore sheath (22-26F) secured by ProGlide. In more than 200 patients conversion to open surgery was necessary in only 4%. Severe femoral artery calcification was the sole risk factor for converting to open surgery. Our findings encourage physicians to choose the percutaneous access even in patients requiring the use of large bore sheath.

Purpose: To demonstrate the Modified Balloon Nose Cone Technique to avoid passage of the aortic valve in endovascular branched arch repair.
Technique: The technique is demonstrated in a 54-year-old patient after previous open repair of the ascending aorta and mechanical aortic valve replacement due to type A aortic dissection. The delivery system of a custom-made stent-graft with 3 inner branches was modified by subtotally sawing off its nose cone. Using a right transaxillary access, a sheath was introduced over a through-and-through (TAT) wire exiting the left groin and meeting the branched stent-graft in a rendezvous fashion. A balloon was used to bridge the gap between both sheaths. Passing the innominate artery, both sheaths were pushed into the ascending aorta to establish a loop configuration of the balloon until the correct landing zone was reached. The main body was deployed, and the supra-aortic target vessels were connected. After the procedure, the mechanical aortic valve showed unimpaired function.
Conclusion: The Modified Balloon Nose Cone Technique broadens the technical armamentarium in endovascular aortic arch repair offering a feasible solution to overcome the need of aortic valve passage. Especially patients with mechanical aortic valve could benefit from this method.
Clinical impact: To describe the feasibility and safety of the Modified Balloon Nose Cone Technique in a severely comorbid patient with residual Type A aortic dissection and history of ascending aortic repair and mechanical replacement of the aortic valve to broaden the technical armamentarium in endovascular aortic arch repair offering a feasible solution to overcome the need of aortic valve passage.

<p><strong>Purpose: </strong>This study aims to summarize the experience and outcomes of using 3D printing technology to assist physician-modified fenestrated-branched endovascular aortic repair (PM-FBEVAR) in the treatment of thoracoabdominal aortic dissection involving visceral branches.</p><p><strong>Materials and methods: </strong>From December 2018 to May 2023, clinical data of 48 consecutive patients (35 males; mean age, 62.9±11.57 years) from 3 hospitals with thoracoabdominal aortic dissection involving visceral branches were retrospectively analyzed. All patients underwent PM-FBEVAR assisted by modified 3D-printed models. The modified 3D-printed models were designed according to estimated aortic morphology after physician-modified endografts were implanted. These models were fabricated using polycaprolactone composite photosensitive resin and stereolithography technology. They were utilized for preoperative planning and guiding the modification of stent grafts to assist in the positioning of the fenestrations. Outcomes including technical success, 30-day mortality, major adverse events (paraplegia, respiratory failure, major stroke, myocardial infarction, acute kidney injury, bowel ischemia, and lower limb ischemia), target vessel-related outcomes (branch occlusion or stenosis, target vessel instability, endoleak), reintervention, and survival were analyzed. Follow-up was completed in all patients.</p><p><strong>Results: </strong>Technical success was achieved in 44 of 48 (91.67%) in patients and 178 of 182 (97.8%) in target vessels. The average operation time was 371.94±63.47 minutes, including a mean of 54.69±9.42 minutes for endograft customization and a mean of 211.92±55.44 minutes for endovascular operation. Perioperative major adverse events include 3 cases (6.25%) of acute renal injury and 1 case (2.08%) of transient paraplegia with no permanent neurological symptoms. The median follow-up was 24 (interquartile range, 12-30) months, and mortality was 0%. Seven endoleaks were detected during follow-up. One type Ic endoleak was managed with a reintervention procedure. One type IIIc endoleak spontaneously disappeared and the other type IIIc endoleak reduced. All 4 type II endoleaks remained stable during follow-up.</p><p><strong>Conclusion: </strong>Rapid and accurate intraoperative fenestrations were achieved with the assistance of 3D printing for thoracoabdominal aortic dissection involving visceral branches. The modified 3D printing assisted PM-FBEVAR appears to be a safe and promising treatment option during early and mid-term follow-up.</p><p><strong>Clinical impact: </strong>This study highlights the use of modified 3D printed models to enhance the precision of fenestrations in physician-modified endografts for treating thoracoabdominal aortic dissection involving visceral branches. The innovation lies in creating patient-specific 3D models based on pre- and post-implantation anatomy, allowing clinicians to optimize fenestration
目的:本研究旨在总结利用3D打印技术辅助医生改良式带血管内主动脉修补术(PM-FBEVAR)治疗涉及内脏分支的胸腹主动脉夹层的经验和结果:回顾性分析了2018年12月至2023年5月期间,3家医院连续收治的48例胸腹主动脉夹层累及内脏分支患者(男性35例,平均年龄(62.9±11.57)岁)的临床资料。所有患者都在改良 3D 打印模型的辅助下接受了 PM-FBEVAR 术。改良三维打印模型是根据医生改良内植物植入后的主动脉形态估计值设计的。这些模型采用聚己内酯复合光敏树脂和立体光刻技术制作而成。这些模型用于术前规划和指导支架移植物的改造,以帮助确定瘘管的位置。分析的结果包括技术成功率、30 天死亡率、主要不良事件(截瘫、呼吸衰竭、严重中风、心肌梗死、急性肾损伤、肠缺血和下肢缺血)、靶血管相关结果(分支闭塞或狭窄、靶血管不稳定、内漏)、再介入和存活率。所有患者均完成了随访:48例患者中有44例(91.67%)技术成功,182例患者中有178例(97.8%)靶血管成功。平均手术时间为(371.94±63.47)分钟,其中内移植物定制平均为(54.69±9.42)分钟,血管内手术平均为(211.92±55.44)分钟。围手术期主要不良事件包括3例(6.25%)急性肾损伤和1例(2.08%)无永久性神经症状的一过性截瘫。中位随访时间为 24 个月(四分位间范围为 12-30 个月),死亡率为 0%。随访期间发现七处内漏。其中一个 Ic 型内漏通过重新介入手术进行了处理。一个 IIIc 型内漏自发消失,另一个 IIIc 型内漏有所缓解。所有4个II型内漏在随访期间均保持稳定:结论:在三维打印技术的辅助下,涉及内脏分支的胸腹主动脉夹层手术实现了快速、准确的术中穿孔。在早期和中期随访中,改良 3D 打印辅助 PM-FBEVAR 似乎是一种安全且有前景的治疗方案:临床影响:这项研究强调了使用改良3D打印模型来提高医生改良内植物的栅栏精度,以治疗涉及内脏分支的胸腹主动脉夹层。其创新之处在于根据植入前后的解剖结构创建患者特异性三维模型,使临床医生能够优化栅栏定位。这种方法有可能降低手术的复杂性并提高准确性,从而获得更好的临床效果。对临床医生来说,它为术前规划和术中指导提供了宝贵的工具,有可能简化复杂主动脉夹层的治疗。

Purpose: The purpose of this article is to report a case of acute superior mesenteric artery embolism due to infective endocarditis treated with endovascular therapy.
Case report: A patient with infective endocarditis was admitted to the hospital with abdominal pain, and abdominal enhanced computer tomography showed acute superior mesenteric artery embolism. He underwent urgent percutaneous mechanical thrombectomy and stenting to open the superior mesenteric artery and restore blood supply to the intestine. However, 17 days after the endovascular treatment, a pseudoaneurysm formed next to the stent, which was eventually removed by open surgery. The patient's prognosis was good at the 1 year follow-up.
Conclusion: Endovascular treatment of acute superior mesenteric artery embolism caused by infective endocarditis was able to rapidly restore the intestinal blood supply. However, the possibility of postoperative pseudoaneurysm needs to be guarded against.
Clinical impact: This study will provide clinical treatment guidance for acute superior mesenteric artery embolism caused by infectious endocarditis. Endovascular treatment may rapidly alleviate intestinal ischemia and reduce the risk of intestinal necrosis, but it cannot completely eliminate infectious emboli, which may lead to further development of pseudoaneurysms.

Purpose: Direct percutaneous access to the carotid artery (diPerCa) during endovascular aortic arch repair (EVAAR) can potentially present a minimally invasive access with lesser local adverse events.
Techniques: A retrospective review of consecutive EVAAR between January 2018 and January 2024, in a tertiary referral center, was performed to identify cases, in which diPerCa was used. Patients who were planned for EVAAR with no previous carotid intervention were included. A standardized technique was employed where an ultrasound-guided retrograde puncture of the carotid artery was performed with a micro-puncture set and a suture-mediated closure device (pre-closure technique). Of the 13 included patients, technical success was achieved in 12 (92.3%), with one intraoperative death unrelated to diPerCa. Major complications included one case of carotid pseudoaneurysm and one case of non-flow-limiting carotid dissection. Minor complications were unilateral recurrent laryngeal nerve palsy in one case and new-onset dizziness in one case. All carotid arteries remained patent without stenosis, with one case of non-progressing dissection noted at the conclusion of the mean follow-up of 22.5±2.4 months.
Conclusion: Direct percutaneous carotid access with suture-mediated closure devices during EVAAR is feasible with acceptable results and low incidence of clinically relevant neurological and local complications. Further studies are needed to confirm these findings and evaluate long-term outcomes.
Clinical impact: Direct percutaneous carotid access (diPerCa) during endovascular aortic arch repair (EVAAR) offers a minimally invasive alternative to retrograde access via open surgical exposure. This technique, supported by suture-based closure devices, demonstrates no stroke and low rates of local complications. Overall outcomes are promising, suggesting diPerCa as a feasible option for select patients. Further research is warranted to validate these findings and assess long-term outcomes.

Purpose: Instances of aortic lesions combined with thoracolumbar spine fractures have been rarely described, primarily occurring in high-speed motor vehicle collisions and falls from heights.
Case report: We present a unique case of a 71-year-old woman with a thoracic aortic rupture caused by a thoracolumbar spine fracture during an accidental domestic fall. She experienced an injury at the level of the celiac trunk on the posterior aspect of the aorta. Hemorrhagic shock and profound hemodynamic instability prompted the swift initiation of a percutaneous endovascular approach, involving the use of REBOA (Resuscitative Endovascular Balloon Occlusion of the Aorta) followed by the parallel graft technique in a sandwich configuration. Subsequently, thoracolumbar spinal fixation was carefully scheduled and performed 20 days after achieving clinical stabilization.
Conclusions: This case underscores the importance of a multidisciplinary approach in managing complex aortic and spinal injuries. The combined use of REBOA and the sandwich graft technique can be life-saving in managing acute thoracic aortic injuries, allowing for the staged stabilization and repair of associated spinal fractures.
Clinical impact: This case highlights a novel approach to managing a rare thoracic aortic rupture caused by an accidental domestic fall. The application of REBOA for immediate hemodynamic stabilization, combined with the use of a sandwich graft configuration, underscores the adaptability of advanced endovascular techniques in complex, life-threatening situations. These interventions demonstrate the importance of tailoring treatment strategies to individual patient needs, especially in cases involving atypical mechanisms of injury. The findings emphasize the value of early multidisciplinary collaboration and dynamic procedural planning, paving the way for improved outcomes and the refinement of clinical protocols in the management of similar trauma cases.

Objective: To evaluate the early and mid-term results of physician-modified candy-plug (pmCP) in patients with type-B or residual type-A aortic dissection (TBRAD).
Methods: All patients with TBRAD who received false lumen (FL) occlusion with pmCP between September 2018 and May 2024 were analyzed. Primary outcomes were technical and clinical success, and overall mortality. Secondary outcomes were postoperative aortic remodeling and aortic reintervention.
Results: Seventeen patients (88% male; mean age 69±12 years) underwent FL occlusion with a pmCP. Nine patients (53%) were emergently treated. The technical and clinical successes were 100% and 82%, respectively. One patient (6%) died postoperatively. Early complete FL occlusion was observed in 82% of the patients. One patient (6%) required an early pmCP-related reintervention. During a mean follow-up of 15±5 months, 75% of the patients had complete thoracic FL thrombosis while 13% of them aortic remodeling in the last computed tomography (CT) scan. Aneurysm size remained stable in 69% of the cases. There were no aortic-related re-interventions during follow-up.
Conclusions: The pmCP technique is a feasible and promising alternative technique, with high primary technical and clinical success rate. Stable aortic diameters can be expected during follow-up, thus reducing the need for further aortic reintervention.
Clinical impact: Persistence of false lumen (FL) patency after thoracic endovascular aortic repair (TEVAR) for thoracic aortic dissection (TBAD) remains a significant challenge for physicians. Various strategies have been developed to address retrograde FL patency, including the candy-plug technique. This technique involves modifying thoracic stent grafts and placing an additional plug to occlude the reduced stent graft waist.Since its introduction, three generations of custom-made candy-plug devices (Cook Medical, Bloomington, IN, USA) have been developed. However, delivery times vary across countries and vascular surgery services, complicating procedural planning, particularly in symptomatic patients or cases of rapid FL diameter progression.In this study, we provide a step-by-step description of the physician-modified candy-plug technique and present our preliminary results.
